> For men in NAS, higher baseline optimism levels were similarly related to longer life span (Table 1, NAS; P trend = 0.002). After adjusting for demographics, baseline health conditions, and depression, compared to the least optimistic men, those in the highest quintile had 10.9% (95% CI: 1.3%, 21.5%) longer life span.

Notably absent: control by wealth.

> For NAS, the demographics model includes baseline age, being white, being married, education, family income, and father’s occupation.

Not wealth specifically, but income is probably as good of a controlling factor.

It did control that in demographics.
